Notes to Consolidated Financial Statements
(Table amounts in thousands, except for share and per share amounts)
Note 1 - Significant Accounting Policies
Nature of Operations. Cullen/Frost Bankers, Inc. (“Cullen/Frost”) is a financial holding company and a bank holding company headquartered in San Antonio, Texas that provides, through its subsidiaries, a broad array of products and services throughout numerous Texas markets. The terms “Cullen/Frost,” “the Corporation,” “we,” “us” and “our” mean Cullen/Frost Bankers, Inc. and its subsidiaries, when appropriate. In addition to general commercial and consumer banking, other products and services offered include trust and investment management, insurance, brokerage, mutual funds, leasing, treasury management, capital markets advisory and item processing.
Basis of Presentation. The consolidated financial statements in this Quarterly Report on Form 10-Q include the accounts of Cullen/Frost and all other entities in which Cullen/Frost has a controlling financial interest. All significant intercompany balances and transactions have been eliminated in consolidation. The accounting and financial reporting policies we follow conform, in all material respects, to accounting principles generally accepted in the United States and to general practices within the financial services industry.
The consolidated financial statements in this Quarterly Report on Form 10-Q have not been audited by an independent registered public accounting firm, but in the opinion of management, reflect all adjustments necessary for a fair presentation of our financial position and results of operations. All such adjustments were of a normal and recurring nature. The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q adopted by the Securities and Exchange Commission (“SEC”). Accordingly, the financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements and should be read in conjunction with our consolidated financial statements, and notes thereto, for the year ended December 31, 2016, included in our Annual Report on Form 10-K filed with the SEC on February 3, 2017 (the “2016 Form 10-K”). Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period.
Use of Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The allowance for loan losses and the fair values of financial instruments and the status of contingencies are particularly subject to change.
Cash Flow Reporting. Additional cash flow information was as follows:

All mortgage-backed securities included in the above table were issued by U.S. government agencies and corporations. At September 30, 2017, approximately 98.1% of the securities in our municipal bond portfolio were issued by political subdivisions or agencies within the State of Texas, of which approximately 67.7% are either guaranteed by the Texas Permanent School Fund, which has a “triple A” insurer financial strength rating, or are secured by U.S. Treasury securities via defeasance of the debt by the issuers. Securities with limited marketability, such as stock in the Federal Reserve Bank and the Federal Home Loan Bank, are carried at cost and are reported as other available for sale securities in the table above. The carrying value of securities pledged to secure public funds, trust deposits, repurchase agreements and for other purposes, as required or permitted by law was $3.5 billion at September 30, 2017 and $3.9 billion at December 31, 2016.
During the fourth quarter of 2012, we reclassified certain securities from available for sale to held to maturity. The securities had an aggregate fair value of $2.3 billion with an aggregate net unrealized gain of $165.7 million ($107.7 million, net of tax) on the date of the transfer. The net unamortized, unrealized gain on the remaining transferred securities included in accumulated other comprehensive income in the accompanying balance sheet as of September 30, 2017 totaled $14.1 million ($9.2 million, net of tax). This amount will be amortized out of accumulated other comprehensive income over the remaining life of the underlying securities as an adjustment of the yield on those securities.
Unrealized Losses. As of September 30, 2017, securities with unrealized losses, segregated by length of impairment, were as follows:

Declines in the fair value of held-to-maturity and available-for-sale securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses to the extent the impairment is related to credit losses. The amount of the impairment related to other factors is recognized in other comprehensive income. In estimating other-than-temporary impairment losses, management considers, among other things, (i) the length of time and the extent to which the fair value has been less than cost, (ii) the financial condition and near-term prospects of the issuer, and (iii) the intent and our ability to retain our investment in the issuer for a period of time sufficient to allow for any anticipated recovery in cost.
Management has the ability and intent to hold the securities classified as held to maturity in the table above until they mature, at which time we expect to receive full value for the securities. Furthermore, as of September 30, 2017, management does not have the intent to sell any of the securities classified as available for sale in the table above and believes that it is more likely than not that we will not have to sell any such securities before a recovery of cost. Any unrealized losses are due to increases in market interest rates over the yields available at the time the underlying securities were purchased. The fair value is expected to recover as the securities approach their maturity date or repricing date or if market yields for such investments decline. Management does not believe any of the securities are impaired due to reasons of credit quality. Accordingly, as of September 30, 2017, management believes the impairments detailed in the table above are temporary and no impairment loss has been realized in our consolidated income statement.
Contractual Maturities. The amortized cost and estimated fair value of securities, excluding trading securities, at September 30, 2017 are presented below by contractual maturity. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations. Residential mortgage-backed securities and equity securities are shown separately since they are not due at a single maturity date.

Sales of Securities. As more fully discussed in our 2016 Form 10-K, during 2016, we sold certain securities issued by municipalities that, based upon our internal credit analysis, had experienced significant deterioration in creditworthiness. Some of the securities we sold were classified as held to maturity prior to their sale. Despite their classification as held to maturity, we believe the sale of these securities was merited and permissible under the applicable accounting guidelines because of the significant deterioration in the creditworthiness of the issuers.
Sales of securities held to maturity were as follows:

Concentrations of Credit. Most of our lending activity occurs within the State of Texas, including the four largest metropolitan areas of Austin, Dallas/Ft. Worth, Houston and San Antonio, as well as other markets. The majority of our loan portfolio consists of commercial and industrial and commercial real estate loans. As of September 30, 2017, there were no concentrations of loans related to any single industry in excess of 10% of total loans other than energy loans, which totaled 10.9% of total loans. Unfunded commitments to extend credit and standby letters of credit issued to customers in the energy industry totaled $1.1 billion and $40.9 million, respectively, as of September 30, 2017.

As of September 30, 2017, non-accrual loans reported in the table above included $54.1 million related to loans that were restructured as “troubled debt restructurings” during 2017. See the section captioned “Troubled Debt Restructurings” elsewhere in this note. Had non-accrual loans performed in accordance with their original contract terms, we would have recognized additional interest income, net of tax, of approximately $783 thousand and $2.4 million for the three and nine months ended September 30, 2017, compared to $647 thousand and $2.4 million for three and nine months ended September 30, 2016.

Loan modifications are typically related to extending amortization periods, converting loans to interest only for a limited period of time, deferral of interest payments, waiver of certain covenants, consolidating notes and/or reducing collateral or interest rates. The modifications during the reported periods did not significantly impact our determination of the allowance for loan losses. As of September 30, 2017, there was one loan totaling $43.1 million that was restructured during the third quarter of 2017 that was in excess of 90 days past due, however, the underlying terms of the modification allow for the deferral of payments. During the nine months ended September 30, 2017, we recognized charge-offs totaling $10.0 million related to loans restructured during the third and fourth quarters of 2016. During the nine months ended September 30, 2016, we recognized a charge-off of $9.5 million related to a loan restructured during the first quarter of 2016. The loan was subsequently sold with proceeds from the sale totaling $30.5 million.
Credit Quality Indicators. As part of the on-going monitoring of the credit quality of our loan portfolio, management tracks certain credit quality indicators including trends related to (i) the weighted-average risk grade of commercial loans, (ii) the level of classified commercial loans, (iii) the delinquency status of consumer loans (see details above), (iv) net charge-offs, (v) non-performing loans (see details above) and (vi) the general economic conditions in the State of Texas.
We utilize a risk grading matrix to assign a risk grade to each of our commercial loans. Loans are graded on a scale of 1 to 14. A description of the general characteristics of the 14 risk grades is set forth in our 2016 Form 10-K. In monitoring credit quality

13


trends in the context of assessing the appropriate level of the allowance for loan losses, we monitor portfolio credit quality by the weighted-average risk grade of each class of commercial loan. Individual relationship managers review updated financial information for all pass grade loans to reassess the risk grade on at least an annual basis. When a loan has a risk grade of 9, it is still considered a pass grade loan; however, it is considered to be on management’s “watch list,” where a significant risk-modifying action is anticipated in the near term. When a loan has a risk grade of 10 or higher, a special assets officer monitors the loan on an on-going basis. The following tables present weighted-average risk grades for all commercial loans by class.

In assessing the general economic conditions in the State of Texas, management monitors and tracks the Texas Leading Index (“TLI”), which is produced by the Federal Reserve Bank of Dallas. The TLI, the components of which are more fully described in our 2016 Form 10-K, totaled 124.6 at August 31, 2017 (most recent date available) and 123.1 at December 31, 2016. A higher TLI value implies more favorable economic conditions.
Allowance for Loan Losses. The allowance for loan losses is a reserve established through a provision for loan losses charged to expense, which represents management’s best estimate of inherent losses that have been incurred within the existing portfolio of loans. The allowance, in the judgment of management, is necessary to reserve for estimated loan losses and risks inherent in the loan portfolio. Our allowance for loan loss methodology, which is more fully described in our 2016 Form 10-K, follows the accounting guidance set forth in U.S. generally accepted accounting principles and the Interagency Policy Statement on the Allowance for Loan and Lease Losses, which was jointly issued by U.S. bank regulatory agencies. The level of the allowance reflects management’s continuing evaluation of industry concentrations, specific credit risks, loan loss and recovery experience, current loan portfolio quality, present economic, political and regulatory conditions and unidentified losses inherent in the current loan portfolio. Portions of the allowance may be allocated for specific credits; however, the entire allowance is available for any credit that, in management’s judgment, should be charged off.
The following table presents details of the allowance for loan losses allocated to each portfolio segment as of September 30, 2017 and December 31, 2016 and detailed on the basis of the impairment evaluation methodology we used:

The notes, which qualify as Tier 2 capital for Cullen/Frost, bear interest at the rate of 4.50% per annum, payable semi-annually on each March 17 and September 17. The notes are unsecured and subordinated in right of payment to the payment of our existing and future senior indebtedness and structurally subordinated to all existing and future indebtedness of our subsidiaries. Unamortized debt issuance costs related to these notes, totaled approximately $1.5 million at September 30, 2017. Proceeds from sale of the notes were used for general corporate purposes.
Our $100 million of 5.75% fixed-to-floating rate subordinated notes matured and were redeemed on February 15, 2017. See Note 8 - Borrowed Funds in our 2016 Form 10-K for additional information about these notes.
Note 7 - Commitments and Contingencies
Financial Instruments with Off-Balance-Sheet Risk. In the normal course of business, we enter into various transactions, which, in accordance with generally accepted accounting principles are not included in our consolidated balance sheets. We enter into these transactions to meet the financing needs of our customers. As more fully discussed in our 2016 Form 10-K, these transactions include commitments to extend credit and standby letters of credit, which involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. We minimize our exposure to loss under these commitments by subjecting them to credit approval and monitoring procedures.

Lease Commitments. We lease certain office facilities and office equipment under operating leases. Rent expense for all operating leases totaled $7.7 million and $23.0 million during the three and nine months ended September 30, 2017 and $7.5 million and $22.0 million during the three and nine months ended September 30, 2016. There has been no significant change in our expected future minimum lease payments since December 31, 2016. See the 2016 Form 10-K for information regarding these commitments.
Litigation. We are subject to various claims and legal actions that have arisen in the course of conducting business. Management does not expect the ultimate disposition of these matters to have a material adverse impact on our financial statements.
Note 8 - Capital and Regulatory Matters
Banks and bank holding companies are subject to various regulatory capital requirements administered by state and federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weighting and other factors.
Cullen/Frost’s and Frost Bank’s Common Equity Tier 1 capital includes common stock and related paid-in capital, net of treasury stock, and retained earnings. In connection with the adoption of the Basel III Capital Rules, we elected to opt-out of the requirement to include most components of accumulated other comprehensive income in Common Equity Tier 1. Common Equity Tier 1 for both Cullen/Frost and Frost Bank is reduced by, goodwill and other intangible assets, net of associated deferred tax liabilities, and subject to transition provisions. Frost Bank's Common Equity Tier 1 is also reduced by its equity investment in its financial subsidiary, Frost Insurance Agency (“FIA”).
Tier 1 capital includes Common Equity Tier 1 capital and additional Tier 1 capital. For Cullen/Frost, additional Tier 1 capital at September 30, 2017 and December 31, 2016 includes $144.5 million of 5.375% non-cumulative perpetual preferred stock. Frost Bank did not have any additional Tier 1 capital beyond Common Equity Tier 1 at September 30, 2017 or December 31, 2016.
Total capital includes Tier 1 capital and Tier 2 capital. Tier 2 capital for both Cullen/Frost and Frost Bank includes a permissible portion of the allowance for loan losses. Tier 2 capital for Cullen/Frost also includes $100.0 million of qualified subordinated debt at September 30, 2017 and $133.0 million of trust preferred securities at both September 30, 2017 and December 31, 2016.

The following table presents actual and required capital ratios for Cullen/Frost and Frost Bank under the Basel III Capital Rules. The minimum required capital amounts presented include the minimum required capital levels as of September 30, 2017 and December 31, 2016 based on the phase-in provisions of the Basel III Capital Rules and the minimum required capital levels as of January 1, 2019 when the Basel III Capital Rules have been fully phased-in. Capital levels required to be considered well capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Capital Rules. See the 2016 Form 10-K for a more detailed discussion of the Basel III Capital Rules.

As of September 30, 2017, capital levels at Cullen/Frost and Frost Bank exceed all capital adequacy requirements under the Basel III Capital Rules on a fully phased-in basis. Based on the ratios presented above, capital levels as of September 30, 2017 at Cullen/Frost and Frost Bank exceed the minimum levels necessary to be considered “well capitalized.”
Cullen/Frost and Frost Bank are subject to the regulatory capital requirements administered by the Federal Reserve Board and, for Frost Bank, the Federal Deposit Insurance Corporation (“FDIC”). Regulatory authorities can initiate certain mandatory actions if Cullen/Frost or Frost Bank fail to meet the minimum capital requirements, which could have a direct material effect on our financial statements. Management believes, as of September 30, 2017, that Cullen/Frost and Frost Bank meet all capital adequacy requirements to which they are subject.
Stock Repurchase Plans. From time to time, our board of directors has authorized stock repurchase plans. In general, stock repurchase plans allow us to proactively manage our capital position and return excess capital to shareholders. Shares purchased under such plans also provide us with shares of common stock necessary to satisfy obligations related to stock compensation awards. On October 27, 2016, our board of directors authorized a $100.0 million stock repurchase program, allowing us to

19


repurchase shares of our common stock over a two-year period from time to time at various prices in the open market or through private transactions. During the three months ended September 30, 2017, we repurchased 1,134,966 shares under the plan at at a total cost of $100.0 million.
Dividend Restrictions. In the ordinary course of business, Cullen/Frost is dependent upon dividends from Frost Bank to provide funds for the payment of dividends to shareholders and to provide for other cash requirements. Banking regulations may limit the amount of dividends that may be paid. Approval by regulatory authorities is required if the effect of dividends declared would cause the regulatory capital of Frost Bank to fall below specified minimum levels. Approval is also required if dividends declared exceed the net profits for that year combined with the retained net profits for the preceding two years. Under the foregoing dividend restrictions and while maintaining its “well capitalized” status, at September 30, 2017, Frost Bank could pay aggregate dividends of up to $480.2 million to Cullen/Frost without prior regulatory approval.
Under the terms of the junior subordinated deferrable interest debentures that Cullen/Frost has issued to Cullen/Frost Capital Trust II and WNB Capital Trust I, Cullen/Frost has the right at any time during the term of the debentures to defer the payment of interest at any time or from time to time for an extension period not exceeding 20 consecutive quarterly periods with respect to each extension period. In the event that we have elected to defer interest on the debentures, we may not, with certain exceptions, declare or pay any dividends or distributions on our capital stock or purchase or acquire any of our capital stock.
Under the terms of our Series A Preferred Stock, in the event that we do not declare and pay dividends on our Series A Preferred Stock for the most recent dividend period, we may not, with certain exceptions, declare or pay dividends on, or purchase, redeem or otherwise acquire, shares of our common stock or any of our securities that rank junior to our Series A Preferred Stock.
Note 9 - Derivative Financial Instruments
The fair value of derivative positions outstanding is included in accrued interest receivable and other assets and accrued interest payable and other liabilities in the accompanying consolidated balance sheets and in the net change in each of these financial statement line items in the accompanying consolidated statements of cash flows.
Interest Rate Derivatives. We utilize interest rate swaps, caps and floors to mitigate exposure to interest rate risk and to facilitate the needs of our customers. Our objectives for utilizing these derivative instruments are described in our 2016 Form 10-K.
The notional amounts and estimated fair values of interest rate derivative contracts are presented in the following table. The fair values of interest rate derivative contracts are estimated utilizing internal valuation models with observable market data inputs, or as determined by the Chicago Mercantile Exchange (“CME”) for centrally cleared derivative contracts. Beginning in 2017, CME rules legally characterize variation margin payments for centrally cleared derivatives as settlements of the derivatives' exposure rather than collateral. As a result, the variation margin payment and the related derivative instruments are considered a single unit of account for accounting and financial reporting purposes. Variation margin, as determined by the CME, is settled daily. As a result, derivative contracts that clear through the CME have an estimated fair value of zero as of September 30, 2017.

Commodity Derivatives. We enter into commodity swaps and option contracts that are not designated as hedging instruments primarily to accommodate the business needs of our customers. Upon the origination of a commodity swap or option contract with a customer, we simultaneously enter into an offsetting contract with a third party financial institution to mitigate the exposure to fluctuations in commodity prices.

Foreign Currency Derivatives. We enter into foreign currency forward contracts that are not designated as hedging instruments primarily to accommodate the business needs of our customers. Upon the origination of a foreign currency denominated transaction with a customer, we simultaneously enter into an offsetting contract with a third party financial institution to negate the exposure to fluctuations in foreign currency exchange rates. We also utilize foreign currency forward contracts that are not designated as hedging instruments to mitigate the economic effect of fluctuations in foreign currency exchange rates on foreign currency holdings and certain short-term, non-U.S. dollar denominated loans.

Gains, Losses and Derivative Cash Flows. For fair value hedges, the changes in the fair value of both the derivative hedging instrument and the hedged item are included in other non-interest income or other non-interest expense. The extent that such changes in fair value do not offset represents hedge ineffectiveness. Net cash flows from interest rate swaps on commercial loans/leases designated as hedging instruments in effective hedges of fair value are included in interest income on loans. For non-hedging derivative instruments, gains and losses due to changes in fair value and all cash flows are included in other non-interest income and other non-interest expense.

As stated above, we enter into non-hedge related derivative positions primarily to accommodate the business needs of our customers. Upon the origination of a derivative contract with a customer, we simultaneously enter into an offsetting derivative contract with a third party financial institution. We recognize immediate income based upon the difference in the bid/ask spread of the underlying transactions with our customers and the third party. Because we act only as an intermediary for our customer, subsequent changes in the fair value of the underlying derivative contracts for the most part offset each other and do not significantly impact our results of operations.

Counterparty Credit Risk. Our credit exposure relating to interest rate swaps, commodity swaps/options and foreign currency forward contracts with bank customers was approximately $23.6 million at September 30, 2017. This credit exposure is partly mitigated as transactions with customers are generally secured by the collateral, if any, securing the underlying transaction being hedged. Our credit exposure, net of collateral pledged, relating to interest rate swaps, commodity swaps/options and foreign currency forward contracts with upstream financial institution counterparties was approximately $10.3 million at September 30, 2017. This amount was primarily related to excess collateral we posted to counterparties. Collateral levels for upstream financial institution counterparties are monitored and adjusted as necessary. See Note 10 – Balance Sheet Offsetting and Repurchase Agreements for additional information regarding our credit exposure with upstream financial institution counterparties.
The aggregate fair value of securities we posted as collateral related to derivative contracts totaled $13.2 million at September 30, 2017. At such date, we also had $10.6 million in cash collateral on deposit with other financial institution counterparties.

Note 10 - Balance Sheet Offsetting and Repurchase Agreements
Balance Sheet Offsetting. Certain financial instruments, including resell and repurchase agreements and derivatives, may be eligible for offset in the consolidated balance sheet and/or subject to master netting arrangements or similar agreements. Our derivative transactions with upstream financial institution counterparties are generally executed under International Swaps and Derivative Association (“ISDA”) master agreements which include “right of set-off” provisions. In such cases there is generally a legally enforceable right to offset recognized amounts and there may be an intention to settle such amounts on a net basis. Nonetheless, we do not generally offset such financial instruments for financial reporting purposes.
Information about financial instruments that are eligible for offset in the consolidated balance sheet as of September 30, 2017 is presented in the following tables.

Repurchase Agreements. We utilize securities sold under agreements to repurchase to facilitate the needs of our customers and to facilitate secured short-term funding needs. Securities sold under agreements to repurchase are stated at the amount of cash received in connection with the transaction. We monitor collateral levels on a continuous basis. We may be required to provide additional collateral based on the fair value of the underlying securities. Securities pledged as collateral under repurchase agreements are maintained with our safekeeping agents.
The remaining contractual maturity of repurchase agreements in the consolidated balance sheets as of September 30, 2017 and December 31, 2016 is presented in the following tables.

Stock-based compensation expense is recognized ratably over the requisite service period for all awards. For most stock option awards, the service period generally matches the vesting period. For stock options granted to certain executive officers and for non-vested stock units granted to all participants, the service period does not extend past the date the participant reaches 65 years of age. Deferred stock units granted to non-employee directors generally have immediate vesting and the related expense is fully recognized on the date of grant. For performance stock units, the service period generally matches the three-year performance period specified by the award, however, the service period does not extend past the date the participant reaches 65 years of age. Expense recognized each period is dependent upon our estimate of the number of shares that will ultimately be issued.
Stock-based compensation expense and the related income tax benefit is presented in the following table.

Net deferred tax assets totaled $28.9 million at September 30, 2017 and $63.7 million at December 31, 2016. No valuation allowance for deferred tax assets was recorded at September 30, 2017 as management believes it is more likely than not that all of the deferred tax assets will be realized because they were supported by recoverable taxes paid in prior years.
The effective income tax rates differed from the U.S. statutory rate of 35% during the comparable periods primarily due to the effect of tax-exempt income from loans, securities and life insurance policies and the income tax effects associated with stock-based compensation. The effective income tax rates for the three and nine months ended September 30, 2017 were also impacted by the correction of an over-accrual of taxes that resulted from incorrectly classifying certain tax-exempt loans as taxable for federal income tax purposes since 2013. As a result, we recognized tax benefits totaling $3.7 million, which included $2.9 million related to the 2013 through 2016 tax years and $756 thousand related to the first and second quarters of 2017. There were no unrecognized tax benefits during any of the reported periods. Interest and/or penalties related to income taxes are reported as a component of income tax expense. Such amounts were not significant during the reported periods.
We file income tax returns in the U.S. federal jurisdiction. We are no longer subject to U.S. federal income tax examinations by tax authorities for years before 2013.

Note 17 – Fair Value Measurements
The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, we utilize valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. ASC Topic 820 establishes a three-level fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. See our 2016 Form 10-K for additional information regarding the fair value hierarchy and a description of our valuation techniques.
Financial Assets and Financial Liabilities. The table below summarizes financial assets and financial liabilities measured at fair value on a recurring basis as of September 30, 2017 and December 31, 2016, segregated by the level of the valuation inputs within the fair value hierarchy of ASC Topic 820 utilized to measure fair value.

Certain financial assets and financial liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). Financial assets measured at fair value on a non-recurring basis during the reported periods include certain impaired loans reported at the fair value of the underlying collateral if repayment is expected solely from the collateral. The following table presents impaired loans that were remeasured and reported at fair value through a specific valuation allowance allocation of the allowance for loan losses based upon the fair value of the underlying collateral during the reported periods.

Note 18 - Accounting Standards Updates
Information about certain recently issued accounting standards updates is presented below. Also refer to Note 21 - Accounting Standards Updates in our 2016 Form 10-K for additional information related to previously issued accounting standards updates.
Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU 2014-09 implements a common revenue standard that clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 was originally going to be effective for us on January 1, 2017; however, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers (Topic 606) – Deferral of the Effective Date" which deferred the effective date of ASU 2014-09 by one year to January 1, 2018. Our revenue is comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014-09, and non-interest income. We expect that ASU 2014-09 will require us to change how we recognize certain recurring revenue streams within trust and investment management fees, insurance commissions and fees and other categories of non-interest income; however, we do not expect these changes to have a significant impact on our financial statements. We expect to adopt the standard in the first quarter of 2018 with a cumulative effect adjustment to opening retained earnings, if such adjustment is deemed to be significant.
ASU 2016-02,“Leases (Topic 842).” ASU 2016-02 will, among other things, require lessees to recognize a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASU 2016-02 does not significantly change lease accounting requirements applicable to lessors; however, certain changes were made to align, where necessary, lessor accounting with the lessee accounting model and ASC Topic 606, “Revenue from Contracts with Customers.” ASU 2016-02 will be effective for us on January 1, 2019 and will require transition using a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. We are currently evaluating the potential impact of ASU 2016-02 on our financial statements. In that regard, we have selected, and will soon implement, a third-party vendor solution to assist us in the application of ASU 2016-02.
ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. ASU 2016-13 will be effective on January 1, 2020. We are currently evaluating the potential impact of ASU 2016-13 on our financial statements. In that regard, we have formed a cross-functional working group, under the direction of our Chief Financial Officer and our Chief Risk Officer. The working group is comprised of individuals from various functional areas including credit, risk management, finance and information technology, among others. We are currently developing an implementation plan to include assessment of processes, portfolio segmentation, model development, system requirements and the identification of data and resource needs, among other things. We are also currently evaluating selected third-party vendor solutions to assist us in the application of the ASU 2016-13. The adoption of the ASU 2016-13 is likely to result in an increase in the allowance for loan losses as a result of changing from an “incurred loss” model, which encompasses allowances for current known and inherent losses within the portfolio, to an “expected loss” model, which encompasses allowances for losses expected to be incurred over the life of the portfolio. Furthermore, ASU 2016-13 will necessitate that we establish an allowance for expected credit losses on debt securities. While we are currently unable to reasonably estimate the impact of adopting ASU 2016-13, we expect that the impact of adoption will be significantly influenced by the composition, characteristics and quality of our loan and securities portfolios as well as the prevailing economic conditions and forecasts as of the adoption date.
ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment.” ASU 2017-04 eliminates Step 2 from the goodwill impairment test which required entities to compute the implied fair value of goodwill. Under ASU 2017-04, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 will be effective for us on January 1, 2020, with early adoption permitted for interim or annual impairment tests beginning in 2017. ASU 2017-04 is not expected to have a significant impact on our financial statements.

33


ASU 2017-05, “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) - Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets.” ASU 2017-05 clarifies the scope of Subtopic 610-20 and adds guidance for partial sales of nonfinancial assets, including partial sales of real estate. Historically, U.S. GAAP contained several different accounting models to evaluate whether the transfer of certain assets qualified for sale treatment. ASU 2017-05 reduces the number of potential accounting models that might apply and clarifies which model does apply in various circumstances. ASU 2017-05 will be effective for us on January 1, 2018 and is not expected to have a significant impact on our financial statements.
ASU 2017-08,“Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) - Premium Amortization on Purchased Callable Debt Securities.” ASU 2017-08 shortens the amortization period for certain callable debt securities held at a premium to require such premiums to be amortized to the earliest call date unless applicable guidance related to certain pools of securities is applied to consider estimated prepayments. Under prior guidance, entities were generally required to amortize premiums on individual, non-pooled callable debt securities as a yield adjustment over the contractual life of the security. ASU 2017-08 does not change the accounting for callable debt securities held at a discount. ASU 2017-08 will be effective for us on January 1, 2019, with early adoption permitted. We are currently evaluating the potential impact of ASU 2017-08 on our financial statements.
ASU 2017-09, “Compensation - Stock Compensation (Topic 718) - Scope of Modification Accounting.” ASU 2017-09 clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. Under ASU 2017-09, an entity will not apply modification accounting to a share-based payment award if all of the following are the same immediately before and after the change: (i) the award's fair value, (ii) the award's vesting conditions and (iii) the award's classification as an equity or liability instrument. ASU 2017-09 will be effective for us on January 1, 2018 and is not expected to have a significant impact on our financial statements.
ASU 2017-12, “Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedging Activities.” ASU 2017-12 amends the hedge accounting recognition and presentation requirements in ASC 815 to improve the transparency and understandability of information conveyed to financial statement users about an entity’s risk management activities to better align the entity’s financial reporting for hedging relationships with those risk management activities and to reduce the complexity of and simplify the application of hedge accounting. ASU 2017-12 will be effective for us on January 1, 2019 and is not expected to have a significant impact on our financial statements.

Application of Critical Accounting Policies and Accounting Estimates
We follow accounting and reporting policies that conform, in all material respects, to accounting principles generally accepted in the United States and to general practices within the financial services industry. The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. While we base estimates on historical experience, current information and other factors deemed to be relevant, actual results could differ from those estimates.
We consider accounting estimates to be critical to reported financial results if (i) the accounting estimate requires management to make assumptions about matters that are highly uncertain and (ii) different estimates that management reasonably could have used for the accounting estimate in the current period, or changes in the accounting estimate that are reasonably likely to occur from period to period, could have a material impact on our financial statements. Accounting policies related to the allowance for loan losses are considered to be critical as these policies involve considerable subjective judgment and estimation by management.
For additional information regarding critical accounting policies, refer to Note 1 - Summary of Significant Accounting Policies and Note 3 - Loans in the notes to consolidated financial statements and the sections captioned “Application of Critical Accounting Policies and Accounting Estimates” and “Allowance for Loan Losses” in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in the 2016 Form 10-K. There have been no significant changes in our application of critical accounting policies related to the allowance for loan losses since December 31, 2016.
Overview
A discussion of our results of operations is presented below. Certain reclassifications have been made to make prior periods comparable. Taxable-equivalent adjustments are the result of increasing income from tax-free loans and investments by an amount equal to the taxes that would be paid if the income were fully taxable based on a 35% federal tax rate, thus making tax-exempt yields comparable to taxable asset yields.

Net income available to common shareholders increased $12.9 million, or 16.5% for the three months ended September 30, 2017 and increased $43.1 million, or 20.1% for the nine months ended September 30, 2017 compared to the same periods in 2016. The increase during the three months ended September 30, 2017 was primarily the result of a $24.7 million increase in net interest income and a $960 thousand decrease in income tax expense partly offset by a $6.3 million increase in non-interest expense, a $5.9 million increase in the provision for loan losses and a $499 thousand decrease in non-interest income. The increase during the nine months ended September 30, 2017 was primarily the result of a $67.8 million increase in net interest income and a $15.4 million decrease in the provision for loan losses partly offset by a $23.7 million increase in non-interest expense, a $9.9 million decrease in non-interest income and a $6.5 million increase in income tax expense. Details of the changes in the various components of net income are further discussed below.
During the third quarter of 2017, our operations in our Houston and Corpus Christi market areas were disrupted by hurricane Harvey. As a result, we incurred certain additional expenses, as discussed below; lost potential revenue as a result of branch closures; and allocated a portion of our allowance for loan losses for probable losses related to the impact of the hurricane, as discussed below. While the ultimate impact of the hurricane on our operations is uncertain, we expect that it will be mitigated, at least in part, by insurance coverage and, based on the information available to us at this time, we do not expect any significant impact on our financial statements.
Net Interest Income
Net interest income is the difference between interest income on earning assets, such as loans and securities, and interest expense on liabilities, such as deposits and borrowings, which are used to fund those assets. Net interest income is our largest source of revenue, representing 72.3% of total revenue during the first nine months of 2017. Net interest margin is the ratio of taxable-equivalent net interest income to average earning assets for the period. The level of interest rates and the volume and mix of earning assets and interest-bearing liabilities impact net interest income and net interest margin.
The Federal Reserve influences the general market rates of interest, including the deposit and loan rates offered by many financial institutions. Our loan portfolio is significantly affected by changes in the prime interest rate. The prime interest rate, which is the rate offered on loans to borrowers with strong credit, remained at 3.50% during most of 2016. In December 2016, the prime rate increased 25 basis points to 3.75% and remained at that level until March 2017, when the prime rated increased

37


another 25 basis points to 4.00%. In June 2017, the prime rate increased an additional 25 basis points to 4.25%. Our loan portfolio is also impacted by changes in the London Interbank Offered Rate (LIBOR). At September 30, 2017, the one-month and three-month U.S. dollar LIBOR interest rates were 1.23% and 1.33%, respectively, while at September 30, 2016, the one-month and three-month U.S. dollar LIBOR interest rates were 0.53% and 0.85%, respectively. The effective federal funds rate, which is the cost of immediately available overnight funds, remained at 0.50% during most of 2016. In December 2016, the effective federal funds rate increased 25 basis points to 0.75% and remained at that level until March 2017, when the effective federal funds rate increased another 25 basis points to 1.00%. In June 2017, the effective federal funds rate was increased an additional 25 basis points to 1.25%.
We are primarily funded by core deposits, with non-interest-bearing demand deposits historically being a significant source of funds. This lower-cost funding base is expected to have a positive impact on our net interest income and net interest margin in a rising interest rate environment. The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) repealed the federal prohibitions on the payment of interest on demand deposits, thereby permitting depository institutions to pay interest on business transaction and other accounts beginning July 21, 2011. To date, we have not experienced any significant additional interest costs as a result of the repeal. However, in light of the aforementioned increases in market interest rates, in late July 2017, we increased the interest rates we pay on most of our interest-bearing deposit products. See Item 3. Quantitative and Qualitative Disclosures About Market Risk elsewhere in this report for information about the expected impact of this legislation on our sensitivity to interest rates. Further analysis of the components of our net interest margin is presented below.
The following tables present the changes in taxable-equivalent net interest income and identifies the changes due to differences in the average volume of earning assets and interest-bearing liabilities and the changes due to changes in the average interest rate on those assets and liabilities. The changes in net interest income due to changes in both average volume and average interest rate have been allocated to the average volume change or the average interest rate change in proportion to the absolute amounts of the change in each. The comparison between the periods includes an additional change factor that shows the effect of the difference in the number of days in each period for assets and liabilities that accrue interest based upon the actual number of days in the period, as further discussed below.

Taxable-equivalent net interest income for the three months ended September 30, 2017 increased $28.7 million, or 12.2%, while taxable-equivalent net interest income for the nine months ended September 30, 2017 increased $79.8 million, or 11.5%, compared to the same periods in 2016. Taxable-equivalent net interest income for the nine months ended September 30, 2017 included 273 days compared to 274 days for the same period in 2016 as a result of the leap year. The additional day added approximately $1.5 million to taxable-equivalent net interest income during the nine months ended September 30, 2016. Excluding the impact of the additional day results in an effective increase in taxable-equivalent net interest income of approximately $81.3 million during the nine months ended September 30, 2017. The increases in taxable-equivalent net interest income during the three and nine months ended September 30, 2017, excluding the impact of the aforementioned additional day during the nine months ended September 30, 2016, were primarily related to the impact of increases in the average volume of tax-exempt securities, loans and interest-bearing deposits as well as increases in the average yields on loans and interest-bearing deposits partly offset by the impact of decreases in the average yields on tax-exempt and taxable securities and the impact of increases in the average rate paid on interest-bearing liabilities. The average volume of interest-earning assets for the three months ended September 30, 2017 increased $1.3 billion, while the average volume of interest-earning assets during the nine months ended September 30, 2017 increased $1.7 billion compared to the same periods in 2016. The increase in average earning assets during the three months ended September 30, 2017, included a $1.1 billion increase in average loans, a $377.0 million increase in average tax-exempt securities, and a $161.3 million increase in average interest-bearing deposits partly offset by a $421.2 million decrease in average taxable securities. The increase in average earning assets during the nine months ended September 30, 2017, included an $821.8 million increase in average loans, a $648.9 million increase in average tax-exempt securities and a $384.9 million increase in average interest-bearing deposits partly offset by a $133.6 million decrease in average taxable securities.
The net interest margin increased 20 basis points from 3.53% during the three months ended September 30, 2016 to 3.73% during the three months ended September 30, 2017 and increased 13 basis points from 3.56% during the nine months ended September 30, 2016 to 3.69% during the nine months ended September 30, 2017. The increases in the net interest margin during the three and nine months ended September 30, 2017 were primarily due to increases in the average yield on interest earning assets. The average yield on interest-earning assets increased 28 basis points from 3.57% during the three months ended September 30, 2016 to 3.85% during the three months ended September 30, 2017 and increased 17 basis points from 3.60% during the nine months ended September 30, 2016 to 3.77% during the nine months ended September 30, 2017. The increases in the average yield on interest earning assets during the three and nine months ended September 30, 2017 were mostly due to increases in the average yields on interest-bearing deposits and loans. The average yield on interest-earning assets is primarily impacted by changes in market interest rates as well as changes in the volume and relative mix of interest-earning assets.
The average yield on loans increased 32 basis points from 4.00% during the first nine months of 2016 to 4.32% during the first nine months of 2017. The average yield on loans was positively impacted by increases in market interest rates compared to the same period in 2016, as discussed above. The average volume of loans during the first nine months of 2017 increased $821.8 million, or 7.1%, compared to the same period in 2016. Loans made up approximately 43.8% of average interest-earning assets during the first nine months of 2017 compared to 43.6% during the same period in 2016.

39


The average yield on securities was 3.96% during the first nine months of 2017, decreasing 5 basis points from 4.01% during the first nine months of 2016. Despite the fact that the average yield on taxable securities decreased 12 basis points from 2.02% during the first nine months of 2016 to 1.90% during the first nine months of 2017 and the average yield on tax-exempt securities decreased 19 basis point from 5.58% during the first nine months of 2016 to 5.39% during the first nine months of 2017, the overall average yield on securities only decreased 5 basis points because of a higher proportion of average securities invested in higher yielding tax-exempt securities during the first nine months of 2017 compared to the same period in 2016. Tax exempt securities made up approximately 58.8% of total average securities during the first nine months of 2017, compared to 55.9% during the same period in 2016. The average volume of total securities during the first nine months of 2017 increased $515.3 million, or 4.3%, compared to the same period in 2016. Securities made up approximately 44.1% of average interest-earning assets during the first nine months of 2017 compared to 45.1% during the same period in 2016.
Average federal funds sold, resell agreements and interest-bearing deposits during the first nine months of 2017 increased $407.3 million compared to the same period in 2016.The increase in average federal funds sold, resell agreements and interest-bearing deposits was primarily related to growth in average deposits. Federal funds sold, resell agreements and interest-bearing deposits made up approximately 12.1% of average interest-earning assets during the first nine months of 2017 compared to 11.3% during the same period in 2016. The combined average yield on federal funds sold, resell agreements and interest-bearing deposits was 1.07% during the first nine months of 2017 compared to 0.51% during the same period in 2016. As discussed above, the effective federal funds rate increased from 0.50% to 0.75% in December 2016, increased from 0.75% to 1.00% in March 2017 and increased from 1.00% to 1.25% in June 2017.
The average rate paid on interest-bearing liabilities was 0.13% during the first nine months of 2017, increasing 5 basis points from 0.08% during the same period in 2016. Average deposits increased $1.5 billion during the first nine months of 2017 compared to the same period in 2016. Average non-interest-bearing deposits for the first nine months of 2017 increased $832.2 million compared to the same period in 2016, while average interest-bearing deposits for the first nine months of 2017 increased $699.7 million compared to the same period in 2016. The ratio of average interest-bearing deposits to total average deposits was 58.3% during the first nine months of 2017 compared to 59.1% during the same period in 2016. The average cost of deposits is primarily impacted by changes in market interest rates as well as changes in the volume and relative mix of interest-bearing deposits. The average cost of interest-bearing deposits and total deposits was 0.09% and 0.05%, respectively, during the first nine months of 2017 compared to 0.05% and 0.03%, respectively, during the first nine months of 2016. The average cost of deposits during 2017 was impacted by the aforementioned increases in interest rates paid on most of our interest-bearing deposit products during the third quarter.
Our net interest spread, which represents the difference between the average rate earned on earning assets and the average rate paid on interest-bearing liabilities, was 3.64% during the first nine months of 2017 compared to 3.52% during the same period in 2016. The net interest spread, as well as the net interest margin, will be impacted by future changes in short-term and long-term interest rate levels, as well as the impact from the competitive environment. A discussion of the effects of changing interest rates on net interest income is set forth in Item 3. Quantitative and Qualitative Disclosures About Market Risk included elsewhere in this report.
Our hedging policies permit the use of various derivative financial instruments, including interest rate swaps, swaptions, caps and floors, to manage exposure to changes in interest rates. Details of our derivatives and hedging activities are set forth in Note 9 - Derivative Financial Instruments in the accompanying notes to consolidated financial statements included elsewhere in this report. Information regarding the impact of fluctuations in interest rates on our derivative financial instruments is set forth in Item 3. Quantitative and Qualitative Disclosures About Market Risk included elsewhere in this report.
Provision for Loan Losses
The provision for loan losses is determined by management as the amount to be added to the allowance for loan losses after net charge-offs have been deducted to bring the allowance to a level which, in management’s best estimate, is necessary to absorb inherent losses within the existing loan portfolio. The provision for loan losses totaled $11.0 million and $27.4 million for the three and nine months ended September 30, 2017 compared to $5.0 million and $42.7 million for the three and nine months ended September 30, 2016. See the section captioned “Allowance for Loan Losses” elsewhere in this discussion for further analysis of the provision for loan losses.

Total non-interest income for the three and nine months ended September 30, 2017 decreased $499 thousand, or 0.6% and decreased $9.9 million, or 3.9%, compared to the same periods in 2016, respectively. Excluding the impact of the net gain (loss) on securities transactions, total non-interest income effectively increased $4.3 million, or 5.3%, and $9.9 million, or 4.1%, respectively, for the three and nine months ended September 30, 2017 compared to the same period in 2016. Changes in the various components of non-interest income are discussed in more detail below.
Trust and Investment Management Fees. Trust and investment management fees for the three and nine months ended September 30, 2017 increased $1.0 million, or 3.9%, and increased $3.9 million, or 5.0%, compared to the same periods in 2016, respectively. Investment fees are the most significant component of trust and investment management fees, making up approximately 83.5% and 81.6% of total trust and investment management fees for the first nine months of 2017 and 2016, respectively. Investment and other custodial account fees are generally based on the market value of assets within a trust account. Volatility in the equity and bond markets impacts the market value of trust assets and the related investment fees.
The increase in trust and investment management fees during the three and nine months ended September 30, 2017 compared to the same period in 2016 was primarily the result of increases in trust investment fees (up $1.6 million and $4.7 million, respectively). The increase in trust investment fees during 2017 was due to higher average equity valuations. The increases in trust investment fees were partly offset by decreases in estate fees (down $212 thousand and $537 thousand during the three and nine months ended September 30, 2017, respectively) and oil and gas fees (down $294 thousand and $159 thousand during the three and nine months ended September 30, 2017, respectively).
At September 30, 2017, trust assets, including both managed assets and custody assets, were primarily composed of equity securities (49.6% of assets), fixed income securities (39.1% of assets) and cash equivalents (6.9% of assets). The estimated fair value of these assets was $31.0 billion (including managed assets of $13.9 billion and custody assets of $17.2 billion) at September 30, 2017, compared to $29.3 billion (including managed assets of $13.4 billion and custody assets of $15.9 billion) at December 31, 2016 and $29.7 billion (including managed assets of $13.3 billion and custody assets of $16.4 billion) at September 30, 2016.
Service Charges on Deposit Accounts. Service charges on deposit accounts for the three months ended September 30, 2017 increased $427 thousand, or 2.1%, compared to the same period in 2016. The increase was primarily due to increases in consumer service charges (up $429 thousand) and overdraft/insufficient funds charges on consumer and commercial accounts (up $315 thousand and $62 thousand, respectively) partly offset by a decrease in commercial service charges (down $368 thousand). Service charges on deposit accounts for the nine months ended September 30, 2017 increased $2.2 million, or 3.6%, compared to the same period in 2016. The increase was primarily due to increases in overdraft/insufficient funds charges on consumer and commercial accounts (up $1.6 million and $361 thousand, respectively) and consumer service charges (up $451 thousand) partly offset by a decrease in commercial service charges (down $221 thousand). Overdraft/insufficient funds charges totaled $8.7 million ($6.8 million consumer and $2.0 million commercial) during the three months ended September 30, 2017 compared to $8.4 million ($6.5 million consumer and $1.9 million commercial) during the same period in 2016. Overdraft/insufficient funds charges totaled $25.9 million ($20.0 million consumer and $5.9 million commercial) during the nine months ended September 30, 2017 compared to $23.9 million ($18.4 million consumer and $5.5 million commercial) during the same period in 2016.
Insurance Commissions and Fees. Insurance commissions and fees for the three months ended September 30, 2017 decreased $137 thousand, or 1.2%, compared to the same period in 2016. The decrease was related to a decrease in contingent income (down $212 thousand) partly offset by an increase in commission income (up $75 thousand). Insurance commissions and fees for the nine months ended September 30, 2017 decreased $1.4 million, or 3.8%, compared to the same period in 2016. The decrease was

41


related to a decrease in contingent income (down $2.7 million) partly offset by an increase in commission income (up $1.3 million). Insurance commissions and fees include contingent income totaling $358 thousand and $3.4 million during the three and nine months ended September 30, 2017, respectively, and $570 thousand and $6.1 million during the same periods in 2016. Contingent income primarily consists of amounts received from various property and casualty insurance carriers related to the loss performance of insurance policies previously placed. These performance related contingent payments are seasonal in nature and are mostly received during the first quarter of each year. This performance related contingent income totaled $2.1 million and $4.6 million during the nine months ended September 30, 2017 and 2016, respectively. The decrease in performance related contingent income during 2017 was related to a lack of growth within the portfolio and a deterioration in the loss performance of insurance policies previously placed. Contingent income also includes amounts received from various benefit plan insurance companies related to the volume of business generated and/or the subsequent retention of such business. This benefit plan related contingent income totaled $311 thousand and $1.3 million during the three and nine months ended September 30, 2017 and $417 thousand and $1.5 million during the three and nine months ended September 30, 2016. The increases in commission income during the three and nine months ended September 30, 2016 were primarily related to increases in benefit plan commissions due to increased business volumes partly offset by decreases in commissions on property and casualty policies.
Interchange and Debit Card Transaction Fees. Interchange fees, or “swipe” fees, are charges that merchants pay to us and other card-issuing banks for processing electronic payment transactions. Interchange and debit card transaction fees consist of income from check card usage, point of sale income from PIN-based debit card transactions and ATM service fees. Interchange and debit card transaction fees for the three and nine months ended September 30, 2017 increased $449 thousand, or 8.3%, and $1.3 million, or 8.3%, compared to the three and nine months ended September 30, 2016. The increases were primarily due to increases in income from debit card transactions (up $381 thousand and $1.0 million for the three and nine months ended September 30, 2017, respectively) and ATM service fees (up $68 thousand and $267 thousand for the three and nine months ended September 30, 2017, respectively). The increases were primarily related to increased transaction volumes.
Federal Reserve rules applicable to financial institutions that have assets of $10 billion or more provide that the maximum permissible interchange fee for an electronic debit transaction is the sum of 21 cents per transaction and 5 basis points multiplied by the value of the transaction. An upward adjustment of no more than 1 cent to an issuer's debit card interchange fee is allowed if the card issuer develops and implements policies and procedures reasonably designed to achieve certain fraud-prevention standards. The Federal Reserve also has rules governing routing and exclusivity that require issuers to offer two unaffiliated networks for routing transactions on each debit or prepaid product.
Other Charges, Commissions and Fees. Other charges, commissions and fees for the three months ended September 30, 2017 decreased $210 thousand, or 2.0%, compared to the same period in 2016. The decrease included decreases in human resources consulting fee income (down $160 thousand) and income from corporate finance and capital market advisory services (down $109 thousand), among other things. These items were partly offset by an increase in income related to the sale of mutual funds (up $128 thousand), among other things. Other charges, commissions and fees for the nine months ended September 30, 2017 increased $158 thousand, or 0.5%, compared to the same period in 2016. The increase included increases in income related to the sale of mutual funds (up $911 thousand) and wire transfer fees (up $235 thousand), among other things. These items were partly offset by decreases in human resources consulting fee income (down $486 thousand) and income from corporate finance and capital market advisory services (down $476 thousand), among other things. Human resources consulting fee income decreased as we no longer provide these services. Changes in the other aforementioned categories of other charges, commissions and fees were due to fluctuations in business volumes.
Net Gain/Loss on Securities Transactions. During the nine months ended September 30, 2017, we sold certain available-for-sale U.S Treasury securities with an amortized cost totaling $8.2 billion and realized a net loss of $50 thousand on those sales. The sales were primarily related to securities purchased during 2017 and subsequently sold in connection with our tax planning strategies related to the Texas franchise tax. The gross proceeds from the sales of these securities outside of Texas are included in total revenues/receipts from all sources reported for Texas franchise tax purposes, which results in a reduction in the overall percentage of revenues/receipts apportioned to Texas and subjected to taxation under the Texas franchise tax. We also sold, during the third quarter of 2017, certain other available-for-sale U.S. Treasury securities with an amortized cost totaling $751.4 million and realized a net loss of $4.9 million on those sales. These securities were sold with the intent to reinvest the sales proceeds in higher yielding debt securities and other investments.
During the nine months ended September 30, 2016, we sold certain available-for sale U.S. Treasury securities with an amortized cost totaling $8.0 billion and realized a net loss of $37 thousand on those sales. The sales were primarily related to securities purchased during 2016 and subsequently sold in connection with our aforementioned tax planning strategies related to the Texas franchise tax. We also sold certain other available-for-sale U.S. Treasury securities with an amortized cost totaling $749.5 million and realized a net gain of $2.8 million on those sales. The securities sold were due to mature during 2016. Most of the proceeds from the sale of these securities were reinvested into U.S. Treasury securities having comparable yields, but longer-terms. During the nine months ended September 30, 2016, we also sold certain municipal securities that were classified as both available for

42


sale and held to maturity due to a significant deterioration in the creditworthiness of the issuers. These securities had a total amortized cost of $431.4 million and we realized a gain of $12.1 million on those sales. Refer to our 2016 Form 10-K for additional information related to these sales.
Other Non-Interest Income. Other non-interest income for the three months ended September 30, 2017 increased $2.8 million, or 34.5%, compared to the same period in 2016. The increase was primarily related to increases in sundry and other miscellaneous income (up $1.1 million), income from customer derivative and trading activities (up $935 thousand), gains on the sale of foreclosed and other assets (up $724 thousand) and income from customer foreign currency transactions (up $248 thousand). Sundry and other miscellaneous income during the three months ended September 30, 2017 included $1.2 million related to the collection of amounts charged-off by Western National Bank prior to our acquisition and $426 thousand related to recoveries of prior write-offs, among other things, while sundry and other miscellaneous income during the same period in 2016 included $453 thousand related to recoveries of prior write-offs, among other things. The fluctuations in income from customer derivative and trading activities and income from customer foreign currency transactions were primarily related to changes in business volumes. During the third quarter of 2017, gains on the sale of foreclosed and other assets included $700 thousand related to amortization of the deferred gain on our headquarters building, which we sold in December 2016.
Other non-interest income for the nine months ended September 30, 2017 increased $3.8 million, or 17.6%, compared to the same period in 2016. The increase was primarily related to increases in gains on the sale of foreclosed and other assets (up $1.5 million), sundry and other miscellaneous income (up $1.5 million), income from customer foreign currency transactions (up $497 thousand) and income from customer derivative and trading activities (up $422 thousand), among other things, partly offset by decreases in lease rental income (down $384 thousand) and earnings on the cash surrender value of life insurance policies (down $311 thousand), among other things. Sundry income during the nine months ended September 30, 2017 included the aforementioned $1.2 million related to the collection of amounts charged-off by Western National Bank prior to our acquisition, $864 thousand related to the settlement of a non-solicitation agreement and $541 thousand related to recoveries of prior write-offs among other things, while sundry and other miscellaneous income during the same period in 2016 included $1.1 million related to recoveries of prior write-offs, among other things. The fluctuations in income from customer foreign currency transactions and income from customer derivative and trading activities were primarily related to changes in business volumes. During the first nine months of 2017, gains on the sale of foreclosed and other assets included $2.2 million related to amortization of the aforementioned deferred gain on our headquarters building.

Total non-interest expense for the three and nine months ended September 30, 2017 increased $6.3 million, or 3.5% and $23.7 million, or 4.4%, compared to the same periods in 2016. Changes in the various components of non-interest expense are discussed below.
Salaries and Wages. Salaries and wages for the three and nine months ended September 30, 2017 increased $5.0 million, or 6.3%, and $11.1 million, or 4.7%, compared to the same periods in 2016. The increase was primarily related to an increase in salaries, due to an increase in the number of employees and normal annual merit and market increases, as well as increases in stock compensation and incentive compensation. Salaries and wages during the three and nine months ended September 30, 2017 also included approximately $1.2 million in severance expense primarily related to the closure of certain branch locations.
Employee Benefits. Employee benefits expense for the three months ended September 30, 2017 decreased $114 thousand, or 0.6%, compared to the same period in 2016. The decrease was primarily due to decreases in medical insurance expense (down $502 thousand), expenses related to our defined benefit retirement plans (down $302 thousand) and other employee benefits (down $120 thousand) partly offset by an increase in expenses related to our 401(k) and profit sharing plans (up $851 thousand). Employee

43


benefits expense for the nine months ended September 30, 2017 increased $1.7 million, or 3.0%, compared to the same period in 2016. The increase was primarily due to increases in expenses related to our 401(k) and profit sharing plans (up $1.6 million) and payroll taxes (up $1.1 million) partly offset by a decrease in expenses related to our defined benefit retirement plans (down $1.1 million).
During the three and nine months ended September 30, 2017, we recognized a combined net periodic pension expense of $125 thousand and $376 thousand, respectively, related to our defined benefit retirement plans compared to a combined net periodic pension expense of $427 thousand and $1.4 million during the same periods in 2016. Net periodic pension expense during the nine months ended September 30, 2016 included $187 thousand in supplemental executive retirement plan (“SERP”) settlement costs related to the retirement of a former executive officer. Our defined benefit retirement and restoration plans were frozen effective as of December 31, 2001 and were replaced by a profit sharing plan. Management believes these actions helped to reduce the volatility in retirement plan expense. However, we still have funding obligations related to the defined benefit and restoration plans and could recognize retirement expense related to these plans in future years, which would be dependent on the return earned on plan assets, the level of interest rates and employee turnover.
Net Occupancy. Net occupancy expense for the three and nine months ended September 30, 2017 increased $1.2 million, or 6.5%, and $4.2 million, or 7.7%, compared to the same periods in 2016. The increase during the three months ended September 30, 2017 was primarily related to increases in lease expense (up $782 thousand), property taxes (up $338 thousand), utilities expense (up $140 thousand) and depreciation on leasehold improvements (up $125 thousand) partly offset by a decrease in building depreciation (down $372 thousand). The increase during the nine months ended September 30, 2017 was primarily related to increases in lease expense (up $2.6 million), property taxes (up $1.0 million), depreciation on leasehold improvements (up $604 thousand), repairs and maintenance/service contracts expense (up $535 thousand) and utilities expense (up $336 thousand) partly offset by a decrease in building depreciation (down $1.1 million). The increases in lease expense and the decreases in building depreciation during the reported periods were primarily related to the sale and lease back of our headquarters building in December 2016, as more fully discussed in our 2016 Form 10-K.
Furniture and Equipment. Furniture and equipment expense for the three and nine months ended September 30, 2017 increased $764 thousand, or 4.2%, and $1.5 million, or 2.8%, compared to the same periods in 2016. The increases were primarily related to increases in software maintenance (up $974 thousand and $2.3 million for the three and nine months ended September 30, 2017, respectively) and depreciation on furniture and equipment (up $198 thousand and $1.4 million for the three and nine months ended September 30, 2017, respectively) partly offset by a decrease in equipment rental expense (down $576 thousand and $1.6 million for the three and nine months ended September 30, 2017, respectively), and, for the nine months ended September 30, 2017, a decrease in service contracts (down $413 thousand), among other things.
Deposit Insurance. Deposit insurance expense totaled $4.9 million and $15.3 million for the three and nine months ended September 30, 2017 compared to $4.6 million and $12.4 million for the three and nine months ended September 30, 2016. Deposit insurance expense was impacted by an increase in assets and, during the nine-months ended September 30, 2017, an increase in the overall assessment rate. The increase in the assessment rate was partly related to a new surcharge that became applicable during the third quarter of 2016. In August 2016, the Federal Deposit Insurance Corporation (“FDIC”) announced that the Deposit Insurance Fund (“DIF”) reserve ratio had surpassed 1.15% as of June 30, 2016. As a result, beginning in the third quarter of 2016, the range of initial assessment rates for all institutions was adjusted downward and institutions with $10 billion or more in assets were assessed a quarterly surcharge. The quarterly surcharge will continue to be assessed until such time as the reserve ratio reaches the statutory minimum of 1.35% required by the Dodd-Frank Wall Street Reform and Consumer Protection Act.
Intangible Amortization. Intangible amortization is primarily related to core deposit intangibles and, to a lesser extent, intangibles related to customer relationships and non-compete agreements. Intangible amortization for the three and nine months ended September 30, 2017 decreased $181 thousand, or 30.9%, and $568 thousand, or 30.4%, respectively, compared to the same periods in 2016. The decrease in amortization was primarily related to the completion of amortization of certain previously recognized intangible assets as well as a reduction in the annual amortization rate of certain previously recognized intangible assets as we use an accelerated amortization approach which results in higher amortization rates during the earlier years of the useful lives of intangible assets.
Other Non-Interest Expense. Other non-interest expense for the three months ended September 30, 2017 decreased $621 thousand, or 1.5%, compared to the same period in 2016. The decrease included decreases in check card expense (down $1.2 million), sundry and other miscellaneous expense (down $711 thousand), regulatory examination fees (down $198 thousand) and losses on the sale/write-down of foreclosed and other assets (down $170 thousand). These items were partly offset by increases in guard services expense (up $580 thousand), the provision for losses on unfunded loan commitments (up$250 thousand), business development expenses (up $207 thousand), point-of-sale related expenses (up $205 thousand), platform fees associated with our managed mutual funds (up $198 thousand) and travel/meals and entertainment expense (up $194 thousand), among other things. Other non-interest expense for the nine months ended September 30, 2017 increased

44


$2.9 million, or 2.3%, compared to the same period in 2016. The increase included increases in guard services expense (up $1.1 million), fraud losses (up $924 thousand), travel/meals and entertainment expense (up $828 thousand), advertising/promotions expense (up $688 thousand) and outside computer services expense (up $760 thousand), among other things. These items were partly offset by a decrease in check card expense (down $1.8 million), among other things. Guard services expense during the three and nine months ended September 30, 2017 was impacted by the effects of hurricane Harvey during the third quarter. The increase in fraud losses was primarily related to check cards, ATMs and checks.

Net income for the three and nine months ended September 30, 2017 increased $12.0 million, or 15.7%, and $40.3 million, or 19.2%, compared to the same periods in 2016. The increase during the three months ended September 30, 2017 was primarily the result of a $24.0 million increase in net interest income and a $1.8 million decrease in income tax expense partly offset by a $6.1 million increase in non-interest expense, a $5.9 million increase in the provision for loan losses and a $1.8 million decrease in non-interest income. The increase during the nine months ended September 30, 2017 was primarily the result of a $65.0 million increase in net interest income and a $15.4 million decrease in the provision for loan losses partly offset by a $20.2 million increase in non-interest expense, a $15.4 million decrease in non-interest income and a $4.5 million increase in income tax expense.
Net interest income for the three and nine months ended September 30, 2017 increased $24.0 million, or 12.5%, and $65.0 million, or 11.4%, compared to the same periods in 2016. Taxable-equivalent net interest income for the first nine months of 2017 included 273 days compared to 274 days for the same period in 2016 as a result of the leap year. The additional day added approximately $1.5 million to taxable-equivalent net interest income during the first nine months of 2016. Despite the effect of this additional day during 2016, net interest income during the three and nine months ended September 30, 2017 increased due to the impact of increases in the average volume of tax-exempt securities, loans and interest-bearing deposits as well as increases in the average yields on loans and interest-bearing deposits partly offset by the impact of decreases in the average yields on tax-exempt and taxable securities combined with the impact of increases in the average rate paid on interest-bearing liabilities. See the analysis of net interest income included in the section captioned “Net Interest Income” included elsewhere in this discussion.
The provision for loan losses for the three and nine months ended September 30, 2017 totaled $11.0 million and $27.4 million compared to $5.0 million and $42.7 million for the same periods in 2016. See the analysis of the provision for loan losses included in the section captioned “Allowance for Loan Losses” included elsewhere in this discussion.
Non-interest income for the three months ended September 30, 2017 decreased $1.8 million, or 3.5%, while non-interest income for the nine months ended September 30, 2017 decreased $15.4 million, or 9.2%, compared to the same periods in 2016. Both the three and nine months ended September 30, 2017 included a net loss on securities transactions of $4.9 million compared to a net loss of $37 thousand during the three months ended September 30, 2016 and a net gain of $14.9 million during the nine months ended September 30, 2016. See the analysis of these net gains and losses included in the section captioned “Net Gain/Loss on Securities Transactions” included elsewhere in this discussion. Excluding the impact of the net gains or losses on securities transactions, total non-interest income during the three and nine months ended September 30, 2017 effectively increased $3.0 million, or 5.9%, and $4.4 million, or 2.9%, respectively compared to the same periods in 2016 primarily due to increases in other non-interest income, service charges on deposit accounts and interchange and debit card transactions fees partly offset by decreases in insurance commissions and fees and other charges, commissions and fees. The increases in other non-interest income for the three and nine months ended September 30, 2017 were primarily related to increases in gains on the sale of foreclosed and other assets, sundry and other miscellaneous income, income from customer foreign currency transactions and income from customer derivative and trading activities, among other things, partly offset by decreases in lease rental income and earnings on the cash surrender value of life insurance policies, among other things. Sundry income during the three and nine months ended September 30, 2017 included $1.2 million related to the collection of amounts charged-off by Western National Bank prior to our acquisition,

45


among other things. Gains on the sale of foreclosed and other assets during 2017 included the amortization of the deferred gain on our headquarters building, which we sold in December 2016. The increase in service charges on deposit accounts during the three and nine months ended September 30, 2017 were primarily due to increases in overdraft/insufficient funds charges on consumer and commercial accounts and consumer service charges partly offset by decreases in commercial service charges. The increase in interchange and debit card transactions fees during the three and nine months ended September 30, 2017 were primarily due to increases in income from debit card transactions and ATM service fees. The increases were primarily related to increased transaction volumes. The decrease in insurance commissions and fees during the three and nine months ended September 30, 2017 were related to decreases in contingent income, primarily related to a lack of growth within the portfolio and a deterioration in the loss performance of insurance policies previously placed, partly offset by increases in commission income, primarily related to increases in benefit plan commissions due to increased business volumes. The decrease in other charges, commissions and fees during the three and nine months ended September 30, 2017 was primarily due to decreases in human resources consulting fee income and income from corporate finance and capital market advisory services, among other things, partly offset by increases in wire transfer fees, and for the nine months ended September 30, 2017, an increase in loan processing fees, among other things. See the analysis of these categories of non-interest income included in the section captioned “Non-Interest Income” included elsewhere in this discussion.
Non-interest expense for the three and nine months ended September 30, 2017 increased $6.1 million, or 4.0%, and $20.2 million, or 4.4%, compared to the same periods in 2016. The increase during the three months ended September 30, 2017 was primarily related to increases in salaries and wages, other non-interest expense and furniture and equipment expense. The increase during the nine months ended September 30, 2017 was primarily related to increases in salaries and wages, other non-interest expense, deposit insurance expense, employee benefits and furniture and equipment expense. The increases in salaries were primarily due to increases in the number of employees and normal annual merit and market increases, as well as increases in stock compensation and incentive compensation. The increases in other non-interest expense were primarily related to increases in guard services expense, sundry and other miscellaneous expense and travel/meals and entertainment, among other things. Guard services expense during the three and nine months ended September 30, 2017 was impacted by the effects of hurricane Harvey during the third quarter. The increases in furniture and equipment expense were primarily related to increases in software maintenance and depreciation on furniture and equipment partly offset by a decrease in equipment rental expense, among other things. The increase in deposit insurance expense during the nine months ended September 30, 2017 was related to an increase in the assessment rate due to a new quarterly surcharge which began in the third quarter of 2016 and an increase in assets. The increase in employee benefits during the nine months ended September 30, 2017 was primarily due to increases in payroll taxes and expenses related to our 401(k) and profit sharing plans partly offset by a decrease in expenses related to our defined benefit retirement plans. See the analysis of these categories of non-interest expense included in the section captioned “Non-Interest Expense” included elsewhere in this discussion.
Frost Insurance Agency, which is included in the Banking operating segment, had gross commission revenues of $10.9 million and $34.6 million during the three and nine months ended September 30, 2017 and $11.0 million and $35.9 million during the three and nine months ended September 30, 2016. The decreases were primarily related to decreases in contingent commissions, partly offset by increases in benefit plan commissions. See the analysis of insurance commissions and fees included in the section captioned “Non-Interest Income” included elsewhere in this discussion.
Frost Wealth Advisors
Net income for the three and nine months ended September 30, 2017 increased $1.6 million, or 33.8% and $4.2 million, or 30.3%, compared to the same periods in 2016. The increase during the three months ended September 30, 2017 was primarily due to a $1.7 million increase in net interest income and a $1.3 million increase in non-interest income partly offset by an $873 thousand increase in income tax expense and a $500 thousand increase in non-interest expense. The increase during the nine months ended September 30, 2017 was primarily due to a $5.4 million increase in non-interest income and a $5.0 million increase in net interest income partly offset by a $3.9 million increase in non-interest expense and a $2.3 million increase in income tax expense.
Net interest income for the three and nine months ended September 30, 2017 increased $1.7 million, or 57.0%, and $5.0 million, or 64.5%, compared to the same periods in 2016. The increases were primarily due to an increase in the funds transfer price received for funds provided related to Frost Wealth Advisors' repurchase agreements and increases in the average volume of funds provided.
Non-interest income for the three and nine months ended September 30, 2017 increased $1.3 million, or 4.3%, and $5.4 million, or 6.0%, compared to the same periods in 2016. The increases in non-interest income during the three and nine months ended September 30, 2017 were primarily related to increases in trust and investment management fees and other charges, commissions and fees. Trust and investment management fee income is the most significant income component for Frost Wealth Advisors. Investment fees are the most significant component of trust and investment management fees, making up approximately 83.5% of total trust and investment management fees for the first nine months of 2017. Investment and other custodial account fees are

46


generally based on the market value of assets within a trust account. Volatility in the equity and bond markets impacts the market value of trust assets and the related investment fees. The increases in trust and investment management fees during the three and nine months ended September 30, 2017 compared to the same periods in 2016 were primarily the result of increases in trust investment fees. The increase in trust investment fees during 2017 was due to higher average equity valuations and an increase in the number of accounts. The increase in other charges, commissions and fees during the three and nine months ended September 30, 2017 was primarily due to increases in income related to the sale of mutual funds. See the analysis of trust and investment management fees and other charges, commissions and fees included in the section captioned “Non-Interest Income” included elsewhere in this discussion.
Non-interest expense for the three and nine months ended September 30, 2017 increased $500 thousand, or 1.9%, and $3.9 million, or 5.1%, compared to the same periods in 2016. The increases during the three and nine months ended September 30, 2017 were primarily related to increases in net occupancy expense, salaries and wages and employee benefits partly offset by decreases in other non-interest expense. The increase in net occupancy expense and decrease in other non-interest expense were related to a change in the way we allocate occupancy expenses among our operating segments. Beginning in 2017, operating segments receive a direct charge for occupancy expense based upon cost centers within the segment. Such amounts are now reported as occupancy expense. Previously, these costs were included within the allocated overhead and reported as a component of other non-interest expense. The increases in salaries and wages during the three and nine months ended September 30, 2017 were primarily related to an increases in the number of employees and normal annual merit and market increases. The increases in employee benefits expense during the three and nine months ended September 30, 2017 were primarily related to increases in payroll taxes, expenses related to our defined benefit retirement plans and medical insurance expense.
Non-Banks
The Non-Banks operating segment had a net loss of $1.7 million and $5.1 million for the three and nine months ended September 30, 2017, respectively, compared to a net loss of $925 thousand and $3.7 million for the same periods in 2016. The increases in net loss during the three and nine months ended September 30, 2017 were primarily due to increases in net interest expense due to an increase in the interest rates paid on our long-term borrowings.
Income Taxes
We recognized income tax expense of $9.9 million and $35.1 million, for an effective tax rate of 9.6% and 11.8% for the three and nine months ended September 30, 2017 compared to $10.9 million and $28.6 million, for an effective tax rate of 11.9% and 11.5% for the three and nine months ended September 30, 2016. The effective income tax rates differed from the U.S. statutory federal income tax rate of 35% during the comparable periods primarily due to the effect of tax-exempt income from loans, securities and life insurance policies and the income tax effects associated with stock-based compensation. The decrease in income tax expense and the effective tax rate during the three months ended September 30, 2017 compared to the same period in 2016 was primarily related to the correction of an over-accrual of taxes that resulted from incorrectly classifying certain tax-exempt loans as taxable for federal income tax purposes since 2013. As a result, we recognized tax benefits totaling $3.7 million, which included $2.9 million related to the 2013 through 2016 tax years and $756 thousand related to the first and second quarters of 2017. The increase in income tax expense and the effective tax rate during the nine months ended September 30, 2017 was primarily related to an increase in total income with a higher proportion of taxable income relative to tax-exempt income, partly offset by the effect of the aforementioned tax benefits related to tax-exempt loans. Excluding the effect of the corrections related to tax-exempt loan interest, our effective tax rates would have been 13.2% and 12.7% for the three and nine months ended September 30, 2017, respectively.
Excluding the deferred tax effects related to other comprehensive income, net deferred tax assets totaled $59.9 million at September 30, 2017. This amount is based upon the current statutory federal income tax rate of 35%. There have been recent legislative proposals to reduce the statutory federal income tax rate. While there can be no assurance that a reduction will ultimately occur, any such reduction in the statutory federal income tax rate would impact the carrying value of our net deferred tax assets with a corresponding charge to income tax expense.

Average Balance Sheet
Average assets totaled $30.2 billion for the nine months ended September 30, 2017 representing an increase of $1.7 billion, or 6.1%, compared to average assets for the same period in 2016. The growth in average assets was primarily funded by deposit growth, an increase in average federal funds purchased and repurchase agreements and earnings retention. The increase was primarily reflected in earning assets, which increased $1.7 billion, or 6.6%, during the first nine months of 2017 compared to the same period in 2016. The increase in earning assets included an $821.8 million increase in average loans, a $648.9 million increase in average tax-exempt securities, and a $384.9 million increase in average interest-bearing deposits partly offset by a $133.6 million decrease in average taxable securities. Average deposit growth included an $832.2 million increase in non-interest bearing deposits and a $699.7 million increase in interest-bearing deposit accounts. Average non-interest bearing deposits made up 41.7% and 40.9% of average total deposits during the first nine months of 2017 and 2016, respectively.

Loans increased $730.9 million, or 6.1%, compared to December 31, 2016. The majority of our loan portfolio is comprised of commercial and industrial loans, energy loans and real estate loans. Commercial and industrial loans made up 36.8% and 36.3% of total loans at September 30, 2017 and December 31, 2016, respectively, while energy loans made up 10.9% and 11.6% of total loans, respectively, and real estate loans made up 48.1% and 48.2% of total loans, respectively, at those dates. Real estate loans include both commercial and consumer balances. Selected details related to our loan portfolio segments are presented below. Refer to our 2016 Form 10-K for a more detailed discussion of our loan origination and risk management processes.
Commercial and industrial. Commercial and industrial loans increased $333.9 million, or 7.7%, during the first nine months of 2017. Our commercial and industrial loans are a diverse group of loans to small, medium and large businesses. The purpose of these loans varies from supporting seasonal working capital needs to term financing of equipment. While some short-term loans may be made on an unsecured basis, most are secured by the assets being financed with collateral margins that are consistent with our loan policy guidelines. The commercial and industrial loan portfolio also includes commercial leases and purchased shared national credits ("SNC"s).
Energy. Energy loans include loans to entities and individuals that are engaged in various energy-related activities including (i) the development and production of oil or natural gas, (ii) providing oil and gas field servicing, (iii) providing energy-related transportation services (iv) providing equipment to support oil and gas drilling (v) refining petrochemicals, or (vi) trading oil, gas and related commodities. Energy loans increased $999 thousand, or 0.1%, during the first nine months of 2017 compared to December 31, 2016. The increase was related to an increase in production loans mostly offset by decreases in service and other loans. The average loan size, the significance of the portfolio and the specialized nature of the energy industry requires a highly

48


prescriptive underwriting policy. Exceptions to this policy are rarely granted. Due to the large borrowing requirements of this customer base, the energy loan portfolio includes participations and SNCs.
Purchased Shared National Credits. Purchased shared national credits are participations purchased from upstream financial organizations and tend to be larger in size than our originated portfolio. Our purchased SNC portfolio totaled $795.4 million at September 30, 2017, increasing $23.3 million, or 3.0%, from $772.2 million at December 31, 2016. At September 30, 2017, 53.4% of outstanding purchased SNCs were related to the energy industry and 16.4% of outstanding purchased SNCs were related to the construction industry. The remaining purchased SNCs were diversified throughout various other industries, with no other single industry exceeding 10% of the total purchased SNC portfolio. Additionally, almost all of the outstanding balance of purchased SNCs was included in the energy and commercial and industrial portfolio, with the remainder included in the real estate categories. SNC participations are originated in the normal course of business to meet the needs of our customers. As a matter of policy, we generally only participate in SNCs for companies headquartered in or which have significant operations within our market areas. In addition, we must have direct access to the company’s management, an existing banking relationship or the expectation of broadening the relationship with other banking products and services within the following 12 to 24 months. SNCs are reviewed at least quarterly for credit quality and business development successes.
Commercial Real Estate. Commercial real estate loans totaled $5.1 billion at September 30, 2017, increasing $268.7 million compared to $4.8 billion at December 31, 2016. At such dates, commercial real estate loans represented 83.4% and 83.8% of total real estate loans, respectively. The majority of this portfolio consists of commercial real estate mortgages, which includes both permanent and intermediate term loans. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Consequently, these loans must undergo the analysis and underwriting process of a commercial and industrial loan, as well as that of a real estate loan. At September 30, 2017, approximately 51% of the outstanding principal balance of our commercial real estate loans were secured by owner-occupied properties.
Consumer Real Estate and Other Consumer Loans. The consumer loan portfolio, including all consumer real estate and consumer installment loans, totaled $1.5 billion at September 30, 2017 and $1.4 billion at December 31, 2016. Consumer real estate loans, increased $77.7 million, or 8.3%, from December 31, 2016. Combined, home equity loans and lines of credit made up 63.7% and 65.1% of the consumer real estate loan total at September 30, 2017 and December 31, 2016, respectively. We offer home equity loans up to 80% of the estimated value of the personal residence of the borrower, less the value of existing mortgages and home improvement loans. In general, we do not originate 1-4 family mortgage loans; however, from time to time, we may invest in such loans to meet the needs of our customers or for other regulatory compliance purposes. Consumer and other loans, increased $49.7 million, or 10.5%, from December 31, 2016. The consumer and other loan portfolio primarily consists of automobile loans, overdrafts, unsecured revolving credit products, personal loans secured by cash and cash equivalents and other similar types of credit facilities.

Non-performing assets include non-accrual loans, troubled debt restructurings and foreclosed assets. Non-performing assets at September 30, 2017 increased $47.4 million from December 31, 2016 primarily due to an increase in non-accrual energy loans and, to a lesser extent, non-accrual commercial and industrial loans. Non-accrual energy loans included four credit relationships in excess of $5 million totaling $86.4 million at September 30, 2017. Of this amount, $29.0 million related to two credit relationships that were previously reported as non-accrual at December 31, 2016 and $57.5 million related to two credit relationships that were placed on non-accrual status during the third quarter of 2017, one of which was a $43.1 million credit relationship that was previously reported as a potential problem loan at June 30, 2017. Non-accrual energy loans included four credit relationships in excess of $5 million totaling $52.1 million at December 31, 2016. Of this amount, we charged-off a total of $10.0 million related to two credit relationships during the first and second quarters of 2017. The outstanding balance of these two credit relationships was $20.5 million at December 31, 2016. Subsequent to the charge-off, the remaining balance of one of these credit relationships was paid-off. The outstanding balance of the other credit relationship totaled $4.9 million at September 30, 2017 and is included in non-accrual energy loans in the table above. Non-accrual commercial and industrial loans included one credit relationship in excess of $5 million totaling $22.0 million at September 30, 2017. This credit relationship was placed on non-accrual status during the third quarter of 2017 and was previously classified as “substandard - accrual” (risk grade 11) at June 30, 2017, though not reported as a potential problem at that time. Non-accrual commercial and industrial loans included one credit relationship in excess of $5 million totaling $9.8 million at December 31, 2016. Of this amount, we charged-off $4.7 million during the third quarter of 2017. The outstanding balance of this credit relationship totaled $4.9 million at September 30, 2017 and is included in non-accrual commercial and industrial loans in the table above. Non-accrual real estate loans primarily consist of land development, 1-4 family residential construction credit relationships and loans secured by office buildings and religious facilities.
Generally, loans are placed on non-accrual status if principal or interest payments become 90 days past due and/or management deems the collectibility of the principal and/or interest to be in question, as well as when required by regulatory requirements. Once interest accruals are discontinued, accrued but uncollected interest is charged to current year operations. Subsequent receipts

50


on non-accrual loans are recorded as a reduction of principal, and interest income is recorded only after principal recovery is reasonably assured. Classification of a loan as non-accrual does not preclude the ultimate collection of loan principal or interest.
Foreclosed assets represent property acquired as the result of borrower defaults on loans. Foreclosed assets are recorded at estimated fair value, less estimated selling costs, at the time of foreclosure. Write-downs occurring at foreclosure are charged against the allowance for loan losses. Regulatory guidelines require us to reevaluate the fair value of foreclosed assets on at least an annual basis. Our policy is to comply with the regulatory guidelines. Write-downs are provided for subsequent declines in value and are included in other non-interest expense along with other expenses related to maintaining the properties. Write-downs of foreclosed assets were not significant during the nine months ended September 30, 2017 or 2016.
Potential problem loans consist of loans that are performing in accordance with contractual terms but for which management has concerns about the ability of an obligor to continue to comply with repayment terms because of the obligor’s potential operating or financial difficulties. Management monitors these loans closely and reviews their performance on a regular basis. At September 30, 2017 and December 31, 2016, we had $89.7 million and $62.7 million in loans of this type which are not included in any one of the non-accrual, restructured or 90 days past due loan categories. At September 30, 2017, potential problem loans consisted of seven credit relationships. Of the total outstanding balance at September 30, 2017, 32.5% was related to the energy industry, 24.8% was related to the manufacturing industry and 13.9% was related to the chemicals industry. Weakness in these organizations’ operating performance and financial condition, loan agreement breaches and borrowing base deficits for certain energy credits, among other factors, have caused us to heighten the attention given to these credits.
Allowance for Loan Losses
The allowance for loan losses is a reserve established through a provision for loan losses charged to expense, which represents management’s best estimate of inherent losses that have been incurred within the existing portfolio of loans. The allowance, in the judgment of management, is necessary to reserve for estimated loan losses and risks inherent in the loan portfolio. Our allowance for loan loss methodology, which is more fully described in our 2016 Form 10-K, follows the accounting guidance set forth in U.S. generally accepted accounting principles and the Interagency Policy Statement on the Allowance for Loan and Lease Losses, which was jointly issued by U.S. bank regulatory agencies. The level of the allowance reflects management’s continuing evaluation of industry concentrations, specific credit risks, loan loss and recovery experience, current loan portfolio quality, present economic, political and regulatory conditions and unidentified losses inherent in the current loan portfolio. Portions of the allowance may be allocated for specific credits; however, the entire allowance is available for any credit that, in management’s judgment, should be charged off.
The table below provides, as of the dates indicated, an allocation of the allowance for loan losses by loan type; however, allocation of a portion of the allowance to one category of loans does not preclude its availability to absorb losses in other categories:

The reserve allocated to commercial and industrial loans at September 30, 2017 decreased $4.5 million compared to December 31, 2016. The decrease was due to decreases in historical and specific valuation allowances partly offset by increases in macroeconomic valuation allowances and general valuation allowances. Historical valuation allowances decreased $6.1 million from $33.3 million at December 31, 2016 to $27.2 million at September 30, 2017. The decrease was primarily related to decreases in the historical loss allocation factors for non-classified loans graded as “watch” (risk grade 9) and “special mention” (risk grade 10) and classified commercial and industrial loans partly offset by increases in the volume of certain categories of both non-classified and classified loans. Classified loans consist of loans having a risk grade of 11, 12 or 13. Classified commercial and industrial loans totaled $150.5 million at September 30, 2017 compared to $131.9 million at December 31, 2016. The weighted-average risk grade of commercial and industrial loans was 6.38 at September 30, 2017 compared to 6.35 at December 31, 2016. Commercial loan net charge-offs totaled $12.2 million during the first nine months of 2017 compared to $8.2 million during the first nine months of 2016. Specific valuation allowances decreased $3.8 million from $5.4 million at December 31, 2016 to $1.7 million at September 30, 2017. Charge-offs in 2017 included $3.6 million related to two credit relationships that, as of December 31, 2016, had associated specific valuation allowances totaling $3.5 million. Charge-offs in 2017 also included $7.4 million related to two credit relationships for which we had no specific allocation as of December 31, 2016, or at the time of charge-off. Macroeconomic valuation allowances for commercial and industrial loans increased $4.7 million from $7.5 million at December 31,

51


2016 to $12.2 million at September 30, 2017. The increase was primarily related to an increase in the general macroeconomic allocation (up $5.5 million) partly offset by a decrease in the environmental risk adjustment (down $980 thousand). The general macroeconomic risk allocation at September 30, 2017 was partly impacted by the effect of hurricane Harvey on our Houston and Corpus Christi market areas. General valuation allowances for commercial and industrial loans increased $689 thousand from $6.7 million at December 31, 2016 to $7.4 million at September 30, 2017. The increase was primarily related to increases in the allocations for highly leveraged credit relationships, large credit relationships and loans not reviewed by concurrence combined with a decrease in the adjustment for recoveries. These items were partly offset by a decrease in the allocation for excessive industry concentrations.
The reserve allocated to energy loans at September 30, 2017 decreased $8.7 million compared to December 31, 2016. As a result, reserves allocated to energy loans as a percentage of total energy loans totaled 3.74% at September 30, 2017 compared to 4.38% at December 31, 2016. This decrease was primarily related to decreases in historical valuation allowances and macroeconomic valuation allowances and partly offset by increases in specific valuation allowances and general valuation allowances. Historical valuation allowances decreased $12.7 million from $34.6 million at December 31, 2016 to $21.9 million at September 30, 2017. The decrease was primarily related to decreases in the volume of classified energy loans and higher risk categories of non-classified energy loans partly offset by increases in the historical loss allocation factors for both non-classified and classified energy loans. Classified energy loans totaled $190.7 million at September 30, 2017 compared to $302.0 million at December 31, 2016, decreasing $111.2 million. Non-classified energy loans graded as “watch” and “special mention” totaled $114.0 million at September 30, 2017 compared to $229.4 million at December 31, 2016, decreasing $115.4 million, while "pass" grade energy loans increased $227.7 million from $854.7 million at December 31, 2016 to $1.1 billion at September 30, 2017. As a result of these changes, the weighted-average risk grade of energy loans decreased to 7.21 at September 30, 2017 from 7.95 at December 31, 2016. Macroeconomic valuation allowances related to energy loans decreased $6.4 million from $18.5 million at December 31, 2016 to $12.1 million at September 30, 2017, in part due to improving trends in the weighted-average risk grade of the energy loan portfolio and decreased oil price volatility. The price per barrel of crude oil was approximately $54 at December 31, 2016 and $52 at September 30, 2017. Despite the overall decrease, macroeconomic valuation allowances related to energy loans at September 30, 2017 were partly impacted by the effect of hurricane Harvey on our Houston and Corpus Christi market areas. Specific valuation allowances for energy loans increased $9.5 million from $3.8 million at December 31, 2016 to $13.3 million at September 30, 2017. Specific valuation allowances at September 30, 2017 were related to two credit relationships totaling $61.8 million while specific valuation allowances at December 31, 2016 were related to three credit relationships totaling $29.8 million. Energy loan net charge-offs totaled $10.0 million during the first nine months of 2017 compared to net charge-offs of $18.6 million during the first nine months of 2016. The charge-offs in 2017 included $10.0 million related to two credit relationships that, as of December 31, 2016, had associated specific valuation allowances totaling $3.4 million. General valuation allowances increased $908 thousand primarily due to an increase in the allocation for excessive industry concentrations partly offset by and increase in the adjustment for recoveries.
The reserve allocated to commercial real estate loans at September 30, 2017 increased $7.9 million compared to December 31, 2016. The increase was primarily related to increases in macroeconomic valuation allowances and historical valuation allowances. Macroeconomic valuation allowances increased $6.7 million from $8.2 million at December 31, 2016 to $14.9 million at September 30, 2017. The increase was primarily related to an increase in the general macroeconomic allocation (up $6.3 million) and the environmental risk adjustment (up $503 thousand). The increase in macroeconomic valuation allowances reflects current economic trends impacting our Houston market area which has been impacted by decreased construction, higher rent concessions and higher vacancy rates. Macroeconomic valuation allowances were also partly impacted by the effect of hurricane Harvey on our Houston and Corpus Christi market areas. Historical valuation allowances increased $1.3 million primarily due to an increase in the volume of non-classified commercial real estate loans. Non-classified commercial real estate loans increased $267.5 million from December 31, 2016 to September 30, 2017 primarily due to an increase in commercial real estate loans graded as “pass.” Classified commercial real estate loans increased $1.2 million from $76.3 million at December 31, 2016 to $77.5 million at September 30, 2017 due to an increase in loans classified as “substandard - accrual” (risk grade 11). The weighted-average risk grade of commercial real estate loans was 6.98 at September 30, 2017 compared to 6.96 at December 31, 2016.
The reserve allocated to consumer real estate loans at September 30, 2017 increased $2.6 million compared to December 31, 2016. This increase was mostly due to a $1.9 million increase in macroeconomic valuation allowances, which was partly impacted by the effect of hurricane Harvey on our Houston and Corpus Christi market areas, and a $534 thousand increase in general valuation allowances, which was primarily related to an increase in allowances allocated for loans not reviewed by concurrence and a decrease in the reduction for recoveries.
The reserve allocated to consumer and other loans at September 30, 2017 increased $4.0 million compared to December 31, 2016. The increase was primarily related to increases in macroeconomic valuation allowances, historical valuation allowances and, to a lesser extent, an increase in general valuation allowances. The increase in macroeconomic valuation allowances was related to a $2.7 million increase in the general macroeconomic allocation, which was primarily related to growth in unsecured personal lines of credit, and also partly impacted by the effect of hurricane Harvey on our Houston and Corpus Christi market

52


areas. The increase in historical valuation allowances was primarily due to an increase in the volume of non-classified consumer and other loans. The increase in general valuation allowances was primarily related to an increase in the allocation for loans not reviewed by concurrence and a decrease in the adjustment for recoveries.

The provision for loan losses decreased $15.4 million, or 36.0%, during the nine months ended September 30, 2017 compared to the same period in 2016. The level of the provision for loan losses in 2016 was reflective of a significant increase in the volume of classified energy loans, specific valuation allowances taken on certain classified energy loans and increases in the weighted-average risk grades of our energy, commercial and industrial and commercial real estate loan portfolios. Classified energy, commercial and industrial and commercial real estate loans totaled $418.7 million at September 30, 2017 compared to $510.1 million at December 31, 2016 and $498.7 million at September 30, 2016. Specific valuation allowances related to energy, commercial and industrial and commercial real estate loans totaled $14.9 million at September 30, 2017 compared to $9.2 million at December 31, 2016 and $7.8 million at September 30, 2016. The overall weighted-average risk grade of our energy, commercial and industrial and commercial real estate loan portfolios was 6.76 at September 30, 2017 compared to 6.84 at December 31, 2016 and 6.85 at September 30, 2016. The level of the provision for loan losses during 2017 was mostly reflective of the level of net charge-offs during during the nine months ended September 30, 2017, which totaled $26.1 million. These charge-offs were mostly related to six credit relationships, as discussed above. The ratio of the allowance for loan losses to total loans was 1.21% at September 30, 2017 compared to 1.28% at December 31, 2016. Management believes the recorded amount of the allowance for loan losses is appropriate based upon management’s best estimate of probable losses that have been incurred within the existing portfolio of loans. Should any of the factors considered by management in evaluating the appropriate level of the allowance for loan losses change, our estimate of probable loan losses could also change, which could affect the level of future provisions for loan losses.

Capital and Liquidity
Capital. Shareholders’ equity totaled $3.2 billion at September 30, 2017 and $3.0 billion December 31, 2016. In addition to net income of $263.6 million, other sources of capital during the nine months ended September 30, 2017 included $82.3 million of other comprehensive income, net of tax, $45.4 million in proceeds from stock option exercises and $9.0 million related to stock-based compensation. Uses of capital during the nine months ended September 30, 2017 included $113.8 million of dividends paid on preferred and common stock.
The accumulated other comprehensive income/loss component of shareholders’ equity totaled a net, after-tax, unrealized gain of $57.7 million at September 30, 2017 compared to a net, after-tax, unrealized loss of $24.6 million at December 31, 2016. The change was primarily due to an $85.3 million net, after-tax, increase in the net unrealized gain on securities available for sale.
Under the Basel III Capital Rules, we have elected to opt-out of the requirement to include most components of accumulated other comprehensive income in regulatory capital. Accordingly, amounts reported as accumulated other comprehensive income/loss do not increase or reduce regulatory capital and are not included in the calculation of risk-based capital and leverage ratios. Regulatory agencies for banks and bank holding companies utilize capital guidelines designed to measure capital and take into consideration the risk inherent in both on-balance sheet and off-balance sheet items. See Note 8 - Capital and Regulatory Matters in the accompanying notes to consolidated financial statements included elsewhere in this report.
We paid a quarterly dividend of $0.54, $0.57 and $0.57 per common share during the first, second and third quarters of 2017, respectively, and a quarterly dividend of $0.53, $0.54 and $0.54 per common share during the first, second and third quarters of 2016, respectively. This equates to a common stock dividend payout ratio of 41.8% and 46.9% during the first nine months of 2017 and 2016, respectively. Our ability to declare or pay dividends on, or purchase, redeem or otherwise acquire, shares of our capital stock may be impacted by certain restrictions under the terms of our junior subordinated deferrable interest debentures and our Series A Preferred Stock as described in Note 8 - Capital and Regulatory Matters in the accompanying notes to consolidated financial statements included elsewhere in this report.
Stock Repurchase Plans. From time to time, our board of directors has authorized stock repurchase plans. In general, stock repurchase plans allow us to proactively manage our capital position and return excess capital to shareholders. Shares purchased under such plans also provide us with shares of common stock necessary to satisfy obligations related to stock compensation awards. On October 27, 2016, our board of directors authorized a $100.0 million stock repurchase program allowing us to repurchase shares of our common stock over a two-year period from time to time at various prices in the open market or through private transactions. During the third quarter of 2017, we repurchased 1,134,966 shares under the plan at a total cost of $100.0 million. On October 24, 2017, our board of directors authorized a new $150.0 million stock repurchase plan allowing us to repurchase shares of our common stock over a two-year period from time to time at various prices in the open market or through private transactions. See Part II, Item 2 - Unregistered Sales of Equity Securities and Use of Proceeds, included elsewhere in this report.
Liquidity. As more fully discussed in our 2016 Form 10-K, our liquidity position is continuously monitored and adjustments are made to the balance between sources and uses of funds as deemed appropriate. Liquidity risk management is an important element in our asset/liability management process. We regularly model liquidity stress scenarios to assess potential liquidity outflows or funding problems resulting from economic disruptions, volatility in the financial markets, unexpected credit events or other significant occurrences deemed problematic by management. These scenarios are incorporated into our contingency funding plan, which provides the basis for the identification of our liquidity needs. As of September 30, 2017, management is not aware of any events that are reasonably likely to have a material adverse effect on our liquidity, capital resources or operations. In addition, management is not aware of any regulatory recommendations regarding liquidity, that would have a material adverse effect on us.
Since Cullen/Frost is a holding company and does not conduct operations, its primary sources of liquidity are dividends upstreamed from Frost Bank and borrowings from outside sources. Banking regulations may limit the amount of dividends that may be paid by Frost Bank. See Note 8 - Capital and Regulatory Matters in the accompanying notes to consolidated financial statements included elsewhere in this report regarding such dividends. At September 30, 2017, Cullen/Frost had liquid assets, including cash and resell agreements, totaling $241.3 million.
Accounting Standards Updates
See Note 18 - Accounting Standards Updates in the accompanying notes to consolidated financial statements included elsewhere in this report for details of recently issued accounting pronouncements and their expected impact on our financial statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk
The disclosures set forth in this item are qualified by the section captioned “Forward-Looking Statements and Factors that Could Affect Future Results” included in Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations of this report and other cautionary statements set forth elsewhere in this report.
Refer to the discussion of market risks included in Item 7A. Quantitative and Qualitative Disclosures About Market Risk in the 2016 Form 10-K. There has been no significant change in the types of market risks we face since December 31, 2016.
We utilize an earnings simulation model as the primary quantitative tool in measuring the amount of interest rate risk associated with changing market rates. The model quantifies the effects of various interest rate scenarios on projected net interest income and net income over the next 12 months. The model measures the impact on net interest income relative to a flat-rate case scenario of hypothetical fluctuations in interest rates over the next 12 months. These simulations incorporate assumptions regarding balance sheet growth and mix, pricing and the repricing and maturity characteristics of the existing and projected balance sheet. The impact of interest rate derivatives, such as interest rate swaps, caps and floors, is also included in the model. Other interest rate-related risks such as prepayment, basis and option risk are also considered.
For modeling purposes, as of September 30, 2017, the model simulations projected that 100 and 200 basis point ratable increases in interest rates would result in positive variances in net interest income of 1.2% and 3.3%, respectively, relative to the flat-rate case over the next 12 months, while 100 and 125 basis point ratable decreases in interest rates would result in a negative variances in net interest income of 5.1% and 9.9%, respectively, relative to the flat-rate case over the next 12 months. The September 30, 2017 model simulations for increased interest rates were impacted by the assumption, for modeling purposes, that we will begin to pay interest on commercial demand deposits (those not already receiving an earnings credit rate) in the fourth quarter of 2017, as further discussed below. For modeling purposes, as of September 30, 2016, the model simulations projected that 100 and 200 basis point ratable increases in interest rates would result in positive variances in net interest income of 0.4% and 1.5%, respectively, relative to the flat-rate case over the next 12 months, while a decrease in interest rates of 50 basis points would result in a negative variance in net interest income of 6.5% relative to the flat-rate case over the next 12 months. The September 30, 2016 model simulations for increased interest rates were impacted by the assumption, for modeling purposes, that we would begin to pay interest on commercial demand deposits (those not already receiving an earnings credit rate) in the fourth quarter of 2016, as further discussed below. The likelihood of a decrease in interest rates beyond 125 basis points as of September 30, 2017 and 50 basis points as of September 30, 2016 was considered to be remote given prevailing interest rate levels.
The model simulations as of September 30, 2017 indicate that our balance sheet is more asset sensitive in comparison to our balance sheet as of September 30, 2016. The shift to a more asset sensitive position was primarily due to increases in the relative proportion of federal funds sold to projected average interest-earning assets. Federal funds sold are more immediately impacted by changes in interest rates in comparison to other categories of earning assets.
Financial regulatory reform legislation entitled the “Dodd-Frank Wall Street Reform and Consumer Protection Act” (the “Dodd-Frank Act”) repealed the federal prohibition on the payment of interest on demand deposits, thereby permitting depository institutions to pay interest on business transaction and other accounts beginning July 21, 2011. To date, we have not experienced any significant additional interest costs as a result of the repeal. However, in light of recent increases in market interest rates, in late July 2017, we increased the interest rates we pay on most of our interest-bearing deposit products. If we began to pay interest on commercial demand deposits (those not already receiving an earnings credit rate), our balance sheet would likely become less asset sensitive. Because the interest rate that will ultimately be paid on these commercial demand deposits depends upon a variety of factors, some of which are beyond our control, we assumed an aggressive pricing structure for the purposes of the model simulations discussed above with interest payments beginning in the fourth quarter of 2017. Should the actual interest rate paid on commercial demand deposits be less than the rate assumed in the model simulations, or should the interest rate paid for commercial demand deposits become an administered rate with less direct correlation to movements in general market interest rates, our balance sheet could be more asset sensitive than the model simulations might otherwise indicate.
As of September 30, 2017, the effects of a 200 basis point increase and a 125 basis point decrease in interest rates on our derivative holdings would not result in a significant variance in our net interest income.
The effects of hypothetical fluctuations in interest rates on our securities classified as “trading” under ASC Topic 320, “Investments—Debt and Equity Securities,” are not significant, and, as such, separate quantitative disclosure is not presented.

Item 4. Controls and Procedures
As of the end of the period covered by this Quarterly Report on Form 10-Q, an evaluation was carried out by management, with the participation of its Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934). Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the disclosure controls and procedures were effective as of the end of the period covered by this report. No change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) occurred during the last fiscal quarter that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
